Summary: Polymers play a significant role in enhanced oil recovery (EOR) due to their viscoelastic properties and macromolecular structure. Different types of polymers exhibit pseudoplastic behavior under shear forces, with biopolymers having better salt tolerance and thermal stability. Hydrolyzed polyacrylamide remains the most commonly used polymer, and alkali-surfactant-polymer flooding shows good efficiency at pilot and field scales.

Summary: This study investigates the application of erucic acid amidopropyl-betaine (EDAB) and sodium alkyl sulfate (SDS) in constructing worm-like micelle systems for enhanced oil recovery. The results demonstrate that under specific conditions, the EDAB/SDS system exhibits viscoelastic fluid behavior, forming longer linear worm-like micelles and larger network structures. The rheological properties of the EDAB/SDS system are influenced by pH, temperature, and salt concentration.

Summary: Polymer-enhanced foam (AOS-DYG) flooding was adopted as an enhanced oil recovery (EOR) technology for the Bohai oilfield to improve foam stability. The addition of polymer increased the thickening ability, liquid film thickness, and gas-liquid interface adsorption layer strength, significantly improving foam stability. Core displacement test results confirmed the excellent mobility control ability of AOS-DYG foam in porous media.

Summary: The effect of silica nanoparticles (NP-SiO2) in xanthan gum (XG) solutions was investigated in this study. The addition of nanoparticles showed a slight effect on the viscosity of the fluids, which became more remarkable over time. Interfacial tension tests measured in water-mineral oil systems did not find any effect on the interfacial properties with the addition of polymer or nanoparticles. Three core flooding experiments were conducted using sandstone core plugs and mineral oil, and the nanofluid formulation recovered about 13% of the residual oil, almost double that of the original XG solution.

Summary: The use of nanofluids in enhanced oil recovery processes has gained attention due to the possibility to increase oil recovery from mature oil fields. Silica nanoparticles are widely used for nanofluid formulations, but there are obstacles such as stability, environmental and economic aspects, and the need for suitable large-scale production processes. This study evaluates oil recovery using silica-based nanofluids from different sources under various operational conditions, and demonstrates that silica from rice husk ash has comparable efficiency to other synthetic silica nanoparticles.

Summary: The study found that non-cubic equations of state perform better at predicting volumetric properties of hydrocarbons, nitrogen, and carbon dioxide at high-pressure high-temperature, but are more complex, necessitating the search for a simpler but accurate CEOS method. By using traditional and machine learning approaches to predict a more accurate molar volume deviation term of the VT-CEOS, the machine learning model showed a high accuracy of 99%.

Summary: Polymers can enhance the efficiency and crude oil recovery in the flooding process. The viscosity of xanthan gum, guar gum, and gum Arabic polymers were measured in the lab and tested as options for enhanced oil recovery (EOR). Results showed that gum Arabic had the lowest viscosity, while xanthan gum and guar gum had significantly higher viscosities. Core flooding experiments indicated that increasing the weight percentage of polymers led to higher oil recoveries. These results were validated using reservoir simulation, which showed consistent trends in oil recoveries. Overall, the study demonstrated the importance of polymers in improving oil recovery.

Summary: This study investigates the influence of the flexible spacer parity of a guest photoactive liquid crystalline dimer on the photonic bandgap features of the cholesteric and twist grain boundary smectic C phases of the host molecule. The results show that the parity of the photoactive dimer affects the width of the photonic bandgap and the blue-shift of the cholesteric phase. Additionally, the parity of the dimer also affects the layer spacing and two-dimensional periodicity of the liquid crystalline phases.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study investigates the effects of different transition metal decorations on B12N12 nanocages on the adsorption properties of nitrosourea drugs using computational methods. The results reveal the presence of weak non-covalent interactions between metals and nanocages, and the interaction between drugs and nanocages plays a significant role in drug adsorption. Compared to free drugs, the adsorption of drugs on nanocages can facilitate electron transfer, reduce energy gaps and chemical hardness, indicating activity at the target site.

Summary: In this study, the selective oxidation of aromatic aldehydes was investigated using Ru(VI) as a catalyst and hexacyanoferrate (III) as a cooxidant in an alkaline medium. The reaction mechanism involves complex reaction orders for the oxidant and the aromatic aldehyde, while the reaction order for Ru(VI) is one. The proposed mechanism includes two catalytic cycles and the formation and decomposition of complexes. Quantitative structure-activity relationship analysis showed that deactivating groups in the para-position enhance the process.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.

Summary: This study examines the sensitivity of the thermal conductivity of water-based alumina nanofluids to changes in concentration, sphericity, and temperature. The results show that volume fraction and temperature have a significant impact on the thermal conductivity, while sphericity also needs to be considered. A support vector machine regression model was created to analyze the sensitivity of the thermal conductivity to different parameters. The findings indicate that temperature, sphericity, and volume fraction are the most sensitive variables.

Summary: This paper reports on the synthesis, structural characterization, spectral and nonlinear-optical properties of glass nanocomposites made of glass forming ionic liquid crystals and nanoparticles. The study reveals that by exciting the nanocomposites within their absorption band, a control over effective optical nonlinearities can be achieved, allowing the modification of the magnitude and sign of the effective nonlinear absorption coefficient. The proposed strategy using metal-alkanoates based glass-forming ionic liquid crystals and nanoparticles shows great potential for the development of nanophotonics and plasmonics technologies.
